Sedney started athletics at the age of five at ARV Ilion in Zoetermeer. Until she was 14, she combined athletics with hockey at hockey club MHCZ in Zoetermeer. At the age of 15, Sedney decided to focus solely on athletics, a decision that paid off with qualifications in four individual events (100m, 200m, 400m and 100m hurdles) at the European Youth Olympic Festival in Győr, Hungary in 2017. Sedney eventually competed in the 200m and 100m hurdles, winning gold in both events. At the same competition she was also part of the Dutch Relay Team (Sedney, Minke Bisschops, Suzanne Libbers and Anna Roelofs), which won a silver medal in the 4 x 100 meter relay.

In 2019, Sedney suffered a hamstring injury, which hampered her preparation for the European U20 Championships in Boras, Sweden. Sedney competed individually in the 200 meters, where she finished in 10th place. She was also part of the 4 x 100 meter relay team (Bisschops, Sedney, Demi van den Wildenberg and N’ketia Seedo), with which she won a silver medal.

Calling her “the uncrowned queen of the junior national championships”, Sedney was a 20-time National Junior Champion, winning three silvers and two bronzes in her youth.

In 2021, Sedney took part in her first international senior tournament at the European Indoor Championships in Toruń, Poland. There she reached the final of the 60 meter hurdles, finishing 7th in 8.00. In the summer of 2021, Sedney competed in the 100m hurdles at both the European U23 Championships in Tallinn, Estonia and at her first Olympics in Tokyo, Japan. In the European U23 Championship, Sedney finished 4th in 13.14. At the Olympics, Sedney finished 7th in her run in 13.03. This was insufficient for a place in the semi-finals. Sedney had the 24th time in total in the series.
